I'm sure that this feature will speed up gameplay quite a bit, and probably make multiplayer matches a lot more frantic. I hope there'll be different types of grenades though, which we can switch between.

Those are the best missions. The ones where you're fighting out in the fields or streets alongside a unit of AI controlled allies. I didn't like the missions in Frontline where you had to infiltrate enemy installations all by yourself. I'd expect to see those types of missions in a 007 game but not in Medal of Honor.
